invention relates to :improvements in typewriter, attachments,.,-and it consists in the combinations, constructions,and arrangements herein described and claimed.

In placing typewriter ribbons on the ribbon reels on the ordinary typewriter, one almost invariably gets his fingers soiled with ink, due to the fact that in order to get the book through the ribbon to hold it, pressure must be applied which forces the ink out on the fingers.

An object of my invention is to provide means whereby the ribbon may be firmly secured to the reel and wound thereon without any liability of soiling the fingers from the ink of the ribbon.

A further object of my invention is to provide a device of the type described which will permit the ribbon to be rolled on the ribbon reel in the ordinary manner.

A further object is to provide a holding device for the ribbon which may be readily removed when desired, and which may be used in connection with another reel.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which- Figure 1 is a plan view of a ribbon reel with my attachment applied thereto,

Figure 2 is a horizontal sectional view along the line 22 of Figure 3, showing the ribbon holding device on the reel,

Figure 3 is a section along the line 33 of Figure 1, and

Figure 4 is a perspective view of the ribbon holding attachment.

In carrying out my invention, I provide the device shown in Figure 4. This consists of side members 1 and 2, and an intermediate integral curved member 3 connecting the two side members.

The member 3 is curved, as will be seen from the drawing, this curvature being concentric with that of the hub 4 of the ribbon reel 5. The side members 1 and 2 are preferably of such a width that the member 3 will frictionally hold the end of the ribbon against the hub 4 for a considerable portion of the periphery of the hub.

As will be seen from Figure 3, the members l and 2 are arranged to frictionally engagethesi'des of thereel 5, but to extend slightly ,.beyonbl the/edge of the. reel, as shown ,at '6. ,fl he'attachment maybe made in the form of aQs't-amping or a casting, or in, :anyf rimin which' the sides engage the sides ofthe reel, andth'e central portion 3 frictionally holds the end of the ribbon. In some instances, I prefer to make the sides 1 and 2 of spring metal, While in other instances they may be rigid, and the frictional contact withthe sides of the reel may depend upon the spring in the reel itself, these reels being ordinarily made of thin sheet metal.

From the foregoing description of the various parts of the device, the'operation thereof may be readily understood. When it is desired to place a ribbon onthe reel, it is only necessary to lay one end 7 of the ribbon see Figure 2) on the hub 4L, and then force the attachment in between the side walls of the reel, sothat the central portion 3 frictionally engages the ribbon, while the sides 1 and 2 engage the side walls of the reel. A ribbon may now be wound on the reel and will enter between the side walls 1 and 2, as shown in Figure 2. In this figure, it will be observed that the second convolution passes over the member 3. The view is exaggerated for the purposes of illustration. As a matter of fact, the ribbon will lie close to the first convolution. As will be seen from Figure 1, the portion 6 projects beyond the periphery of the reel 5. When it is desired to remove the attachment, the portion 6 may be gripped by the fingers and the attachment may beremoved by pulling it out from between the side walls of the reel. In the operation of applying or removing the device there is no liability of getting the fingers soiled from the. ink.

Since the attachment is made in the standard sizes, it may be used in connection with different reels, and when in position per mits the use of the reel in the ordinary manner.

I claim:

1. The combination with a typewriter ribbon reel having a hub, of a typewriter ribbon clamping device comprising a central arc-shaped member curved to conform with the contourof the hub and having an unbroken concave surface and an unbroken convex surface, and integral sides at the end of said central member, the interior and exterior portions of the sides being unbroken, and the outer portion of said sides being arranged to frictionally engage the side walls of the reel.

2. The combination With a typewriter ribbon reel having a hub, of a typewriter ribbon clamping device comprising a central arc-shaped member curved to conform With the contour of the hub and having an unbroken concave surface and an unbroken convex surface, and integral sides at the end of said central member, the interior and exterior portions of the sides being unbroken, and the outer portion of said sides being arranged to frictionally engage the side walls of the reel, said sides having a portion extending slightly beyond the outer edge of said side Walls.

3. As an article of manufacture, a rib bon clamping device for typewriters, comprising a central arc-shaped member having an unbroken surface on its concave and convex surfaces, and integral side members comprising flat plates extending in planes at right angles to the axis of said arc-shaped member at the ends thereof, on the convex; side of each arc-shaped member.

BEVERLY WHITE.
